These are great for making plain hard boiled eggs into something fun to eat!
After you take the hot hard boiled egg out of its shell, put in the egg shaper and close it. Put the egg shaper in a bowl of cold water for 10 minutes. When you open the mold your hard boiled egg is not a cute car or fish!
The temperature range for this product is -20 ~ 120 degrees Celsius. I would wash by hand.
